Parámetros

  • eUsageType
    A value from the DTSUsageType enumeration that is assigned to the IDTSInputColumn90.

Valor devuelto

The IDTSInputColumn90 object whose UsageType is set.

Notas

SetUsageType is called when a column from the IDTSVirtualInputColumnCollection90 is selected for a component. If the usageType is UT_READONLY or UT_READWRITE, a new input column is created for the component that reflects the IDTSVirtualInputColumn90 specified by the lLineageID parameter. If usageType is UT_IGNORED and the column exists in the collection, the column is removed and null is returned.
